Critical Hotfix - Redis Startup Failure

Priority: CRITICAL - Fixes production blocking issue

Problem

Redis fails to start in production with error:

This account is currently not available.

This prevents all agents from executing since Redis startup is critical.

Root Cause

The redis user has /usr/sbin/nologin as its default shell (standard for system users). When we try to run:

su redis -c 'redis-server ...'

The system rejects it because the redis user cannot obtain a shell.

Solution

Use su -s /bin/sh to explicitly specify a shell:

su -s /bin/sh redis -c 'redis-server /etc/redis/redis.conf --daemonize yes'

Changes

  • src/agents/utils/setup.ts: Updated Redis startup command with -s /bin/sh flag
  • src/agents/prompts/templates/partials/environment.eta: Updated agent documentation

Testing

✅ All 62 tests pass
✅ Type checking passes
✅ CI checks pass

Deployment Impact

This fix is required for production to function. All agent executions are currently failing due to Redis startup failure.

Add Redis support alongside PostgreSQL, enabling agents to use in-memory
data storage for caching, queues, and session management.

Changes:
- Install redis-server and redis-tools in Docker image
- Configure Redis with AOF persistence, 256MB memory limit, and LRU eviction
- Add startRedis() function following the same pattern as startPostgres()
- Integrate Redis startup into agent lifecycle (base.ts, review.ts)
- Document Redis CLI commands and usage in agent prompts
- Both PostgreSQL and Redis are critical: agents fail if either service doesn't start

Redis configuration:
- Port: 6379 (standard)
- Bind: localhost only for security
- Persistence: AOF with everysec fsync
- Memory: 256MB with allkeys-lru eviction policy
- Access: via redis-cli through Tmux gadget

The debug agent wasn't triggering because CASCADE was shutting down too
quickly after uploading session logs. Trello webhooks for attachment uploads
take a few seconds to arrive, but we were only waiting 5 seconds before
shutting down the machine.

Increased postJobGracePeriodMs from 5s to 45s to ensure:
1. Agent uploads session log attachment
2. Trello webhook is delivered while machine is still running
3. Debug agent trigger processes the webhook
4. Debug agent runs before shutdown

This fixes the race condition where attachment webhooks arrived after
the machine had already shut down.

Both pull_request_review (review submission) and pull_request_review_comment
(review comments) now trigger the review agent for PRs with Trello card URLs.

Changes:
- Updated webhook queue to store event types alongside payloads
- Added PRReviewSubmittedTrigger for review submissions (approve/request changes)
- Fixed hardcoded event type in GitHub webhook dequeuing
- Both review types now trigger the review agent when PR has Trello card URL

Previously, only review comments triggered the agent. Now review submissions
(when someone clicks 'Approve' or 'Request Changes') also trigger it.

Adds automatic card movement logic to executeGitHubAgent that mirrors
the existing behavior in Trello webhook handler. When implementation
agent creates a PR, the card is now moved to the IN REVIEW list and
a comment with the PR URL is added.

This ensures consistent behavior regardless of whether the agent was
triggered by a Trello webhook or a GitHub webhook.

Adds comprehensive documentation for GitHub webhook setup:
- GitHub webhook endpoint in API endpoints section
- Detailed setup instructions with configuration steps
- List of supported GitHub triggers and their behavior
- Updated features list to include GitHub integration

This complements the recent GitHub webhook improvements including
PR review submission support and automatic card movement.

The redis user has /usr/sbin/nologin as its default shell, which
prevents `su redis -c` from working. This was causing Redis to fail
to start in production with "This account is currently not available."

Fix by using `su -s /bin/sh` to explicitly specify a shell for the
redis user when starting the service.

Also updated agent environment documentation to reflect the correct
startup command.
